Plain-English summary
A 21-year-old mare underwent surgery to remove a tumor called an ameloblastoma from her jaw. After the surgery, she experienced some complications, including a fracture in her jaw and a small wound that opened up. Despite these issues, she was able to eat well, and her incision healed within two weeks. Eighteen months later, her jaw had healed enough to show signs of bony fusion, and while her tongue protruded slightly, she had a good functional outcome.

Abstract
OBJECTIVE: To report long-term outcome in a mare that had extensive rostral mandibulectomy to remove an ameloblastoma. STUDY DESIGN: Clinical report. ANIMALS: A 21-year-old mare. METHODS: An ameloblastoma, located in the rostral aspect of the mandible, was removed by complete en-bloc resection of the tumor, removing most of the mandibular symphysis. RESULTS: The day after surgery, the remaining mandibular symphysis (<5 mm) fractured causing marked instability of the hemi-mandibles. Partial wound dehiscence occurred 5 days after surgery; however, the mare was able to eat well and the incision healed within 2 weeks. At 18 months, there was bony fusion of the hemi-mandibles and mild protrusion of the tongue. CONCLUSION: Extensive rostral mandibulectomy (up to the caudal edge of the mandibular symphysis) can apparently be performed in a horse without internal or external stabilization, and yield a cosmetic and functional outcome.
